ClubGP was the main forum, and GOClubGP was the "Greater Ohio" chapter.
One thing that sticks out to me about GOClubGP, I remember one of the members on there (she may have been an admin/moderator) had a pristine Grand Prix she tried selling for some ridiculous price back around 2008 or so. She said the oil was changed every 3,000 miles religiously. Well she wasn't kidding. She said one time she was driving home from a long trip and realized she was right at 3,000 miles since her last oil change. So she pulled over and called AAA and had the car towed home.
Dumbest thing I've ever heard. I think you would potentially risk more damage from a tow truck than you would going over your 3k interval. Like the oil will instantly break down at 3,001 miles and kill the motor.
